# Reject an external connector change

> Rejects an external connector change.



## OpenAPI

````yaml openapi.bundled.yaml POST /external-connectors/changes/{id}/reject
openapi: 3.1.0
info:
  title: Parmana API
  version: 1.0.0
  description: >
    Parmana is an Execution Trust Infrastructure that ensures there is no gap
    between what humans decide and what AI systems do. The API enables creation,
    execution, verification, replay, and auditing of Business Transactions
    through cryptographically verifiable Execution Trust Records.


    **Every route requires a caller bearer key**, except the liveness/readiness
    probes and documentation/verification routes that must be reachable with no
    credential: GET /health, GET /ready, GET /openapi.yaml, GET /documentation,
    GET /reference, POST /refusal/verify, POST /execution-intents/verify, POST
    /audit/verify, GET /keys/{keyId}, and GET /.well-known/jwks.json. Send
    `Authorization: Bearer <key>` on every other request. Keys are issued by
    `scripts/generate-api-key.ts` and configured server-side via
    `PARMANA_API_KEYS`; only a hash of each key is ever held by the server,
    verified in constant time. A missing or invalid credential returns 401
    before a Business Transaction is even constructed, independent of Policy
    evaluation and gateway attestation, see
    `packages/api/src/middleware/caller-auth.ts` and
    [Authentication](/api-reference/authentication). Local development may set
    `PARMANA_AUTH_DISABLED=true` to skip this middleware entirely; that flag
    must never be set in a real deployment.
